Problem 1 A certain plant has the following state-space description 1 = 22 12 = 10:01 - 3.12 + u y = 21 (a) Determine G(s), the transfer function of the plant. Hint: Since this system appears in the following problems, it is recommended that you calculate the transfer function by two different methods. (b) The forward loop of the closed-loop system F(s) H(8) 1+F(8) comprises the plant of part (a) and PI compensator. Thus the forward loop transfer function is Kis + K2G() F(s) Determine the region in the K2, K1 plane (if any) in which the closed-loop system is stable. Problem 2 The system of Problem 1 is operated with Ki = K2=K Sketch the root locus of the poles of the closed-loop system, showing important features, including: segments on the real axis, asymptotes for large values of K, and crossing(s) of the imaginary axis.
